Title: Improvements relating to current transformers
IPC: H01F27/42
Filed: 1930-05-06
Abstract: 357,082. Current transformers ; current and pressure meters. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Ohio Brass Co. ; Mansfield, Ohio, U.S.A.) May 6, 1930, No. 13874. [Class 38 (ii).] Comprises a current transformer having a shunt about one of its windings for diverting a portion of the current in the winding to correct for transformation ratio and/or phase angle error. The ratio of the current in the shunt to the current in the shunted winding varies for different valves of current flowing through the transformer. In the form shown in Fig. 1 an impedance 17 is in series with the primary winding 13 and an impedance 16 in parallel. The impedance 16 may be an iron core reactance that does not saturate, and the impedence 17 of an iron cored reactance or the primary of a current transformer that saturates with increase of current so that the impedance ratio varies. Alternatively 17 may be a current transformer with a reactance 18 controlled by thermal relays 18<1> connected across its secondary. In a modification the impedance 16 may be a resistance having a positive coefficient of resistance for temperature changes and the impedance 17 a resistance having a negative coefficient. In another modification thermal relays may be used to vary the impedances 16, 17. Fig. 2 shows a modification in which an autotransformer 20 is used to obtain a current distribution to the main and shunt circuits. The ammater is connected to the secondary 14 through an insulating transformer 23 which may also be provided with compensating impedances 24, 25. A capacitance tap may be provided. A shield 27 insulated from earth and from the primary winding is mounted in the bushing and connected to one end of the secondary. The connection from this shield is through the primary of the insulating transformer, through a current transformer 29 to earth. The transformer 29 has a low voltage wind ing to which is connected the instrument to be operated by the capacitance tap. A limiting gap 31 is provided across the primary of the transformer 29. In another modification, Fig. 5, the shunt circuit includes a winding 13<1> inductively coupled to the primary 13 for the purpose of phase angle correction. When heavy currents are to be carried the current to the primary may be divided as shown in Fig. 6 between those circuits. If the current in lead 63 is adjusted to be approximately equal to the current in the lead 62 which passes through the core their tangential magnetization effects on the core will cancel.

Filed: 1949-05-28
Abstract: 659,652. Fuel injectors. BISCHOF, B. May 28, 1949, No. 14355. Convention date, Dec. 30, 1948. [Class 7(iii)] A piston working in a body member 1 comprises two parts 2, 3 of different diameters each slidable in fluidtight guides 4, 5 located at corresponding ends of a compression chamber 6 in the body 1 and fed from a supply orifice 18 with fuel under pressure that moves the piston in the direction of the fuel flow such that part 3 enters the chamber and causes a reduction of volume therein. There are co-operating parts of the piston and body, which, when the piston moves, closes the chamber, as by a conduit 15 connecting the chamber and piston bore 14 and closed by the chamber bottom 8 when moved through a distance h, and which causes the ejection of fuel from outlet orifices 16, as by controlling the opening of the orifices by the body ridge 22 when the piston moves a distance h<SP>1</SP>. The piston is returned to its withdrawn position principally by the elasticity of the fuel which is compressed in the chamber and the return may be assisted by a spring 7. The piston may have a head T the faces 10, 11 of which co-operate with faces 12, 13 of a chamber 20 to limit the piston movements. In modifications (a) the wall of guide 5 has an annular groove in communication with the chamber 20 and the upper edge of which cooperates with face 9 of part 3 to close the chamber, the groove being connected by radial channels with the bore 14 when the piston moves down, there being a single central orifice 16 or several orifices tangential to the bore so that ejection of fuel causes rotation of the piston, Figs. 2 and 3 (not shown), (b) the bore 14 is closed below conduit 15 and a single central orifice is controlled by the edges of a groove formed in the wall of guide 4 and connected by a conduit to chamber 20, Fig. 6 (not shown), and (c) the faces 10, 11 of the head are connected by axial conduits which are inclined with respect to the piston axis so that fuel discharged into chamber 20 produces a rotation of the piston, Fig. 7 (not shown).

Title: Control apparatus for color-television receiver
IPC: H04N9/70
Filed: 1954-05-17
Abstract: 781,178. Television. HAZELTINE CORPORATION. May 17, 1954 [July 15, 1953], No. 14382/54. Class 40 (3). In a compatible colour-television receiver for an N.T.S.C. type signal the chrominance channel is disabled by means of a control signal which is generated by a detector system responsive to the absence of the colour synchronizing " burst " signal (e.g. when the receiver is employed for monochrome reception). Fig. 1 shows one embodiment in which such disablement is effected by means of a control signal, developed in a circuit 41 from the output of a phase detector 29 in which the phase of the received colour " burst " signal is compared with the " I " phase of the locally generated colour subcarrier wave. When the " burst " signal is present the control signal is such as to maintain operative the amplifier 19 through which the chrominance signal is supplied to the colour difference signal detector 20. In the absence of a " burst " signal, however, the control signal renders amplifier 19 inoperative and the receiver is then conditioned to reproduce monochrome pictures without the distortions which would be caused by translation of noise, undesired monochrome and spurious beat signals through the chrominance channel if this was operative when receiving a monochrome transmission. Circuit details of the various " blocks " enclosed in rectangle 22 are described with reference to Fig. 1a (not shown) and alternative circuit arrangements concerned both with rendering the chrominance channel inoperative and also with employing the control signal to improve the operating characteristics of the A.P.C. system including the units 28, 30, 38 of Fig. 1 are described with reference to Figs. 6 and 7 (not shown).
